well im just starting them inside for like the first 2 weeks, then moving/transplanting to bigger pots outside

but thanks for ur help. ur information was very useful/relavent

Just remember, lumens aren't cumulative. 10x 1300 lumen cfl bulbs will still only provide 1300 lumens.

Generally the higher the wattage, the higher the luminosity, so if you're going to use CFL's get the absolutely highest wattage possible.

ok people lets think this out lumens = energy so more energy more lumens
no way around that yes each bulb is producing the same amount out lumens as each other bulb but lets think here if you add one more then there are more photons than there were before so more energy landing on that spot and more photosenthysys

take a mirror reflect a spot of light on the wall -- get another mirror of the same size and aim it on the same spot -- wow the spot just got brighter hmmm more lumens in one spot they do add up its just a matter of aiming them in the same place

energy is energy no matter what form its in heat,gravity,wind or light and more is more --- a 1000 watt mh or hps is not going to be most effecient with no reflector....why not hmm must be the lumens that are being lost due to landing on the wall or the floor or the celing and getting turned into heat by adsorbtion now if we put that bulb in a reflector those lost lumens get focused where we want them and HOT DAMN more lumens in the same spot.

dosent matter where those lumens came from it was aiming them where we wanted them that made the difference and they did add up
